New Virus Catalog Helps Identify Most Threatening Pathogens
Scientists have created a comprehensive catalog of human RNA viruses, aiming to predict which could cause the next pandemic.
Researchers have developed a new catalog of human RNA viruses to help identify those posing the greatest threat to public health.
The catalog, created by scientists at the University of Edinburgh, focuses on RNA viruses, known for their rapid mutation and transmission capabilities. While only a few new viruses are discovered annually, historical precedents like HIV and SARS-CoV-2 demonstrate how minor discoveries can escalate into global pandemics.
The system evaluates viruses based on factors such as human-to-human transmission and disease severity. Most viruses on the list are zoonotic, meaning they transfer from animals to humans, like rabies, and do not easily spread among people.
Of greater concern are viruses already capable of human-to-human spread or those that have caused limited outbreaks. Their potential for increased transmissibility and subsequent impact is under close scrutiny. Faster identification and understanding of new viruses could help prevent future pandemics and mitigate their damage.
The research aims to provide a tool for health officials and scientists to better anticipate and respond to emerging viral threats, thereby working to avert future pandemics.
